Title: Tube for heat exchanger made of aluminum
Inventor: OTSUKA FUJIO
IPC: F28F19/06
Filed: 1986-09-27
Abstract: PURPOSE:To secure the amount of zinc in a sacrificial corrosion forming layer of an internal surface after brazing and permit the sacrificial corrosion layer to function sufficiently, by a method wherein at least two layers of the sacrificial corrosion forming layer are formed and the amount of content of zinc of respective layers is increased toward the central side of a tube. CONSTITUTION:A tube 10 is constituted of a core member 11, a brazing material 12 for brazing in a furnace, which is formed on the outer surface thereof, a first sacrificial corrosion forming layer 13 consisting of Al-Zn alloy (containing 0.3% of zinc for example), which is formed on the inner surface thereof, and a second sacrificial corrosion forming layer 14 consisting of an Al-Zn alloy (containing 1.0% of zinc for example), which is formed on the outside of the first sacrificial corrosion forming layer 13. The preliminary treatment of the tube 10 is applied by a brazing method employing non-corrosive plastics, thereafter, the tube is assembled temporarily through a jig together with fins and a seat plate, then, is heated in a heating furnace to braze respective connecting parts. According to the brazing, zinc in both sacrificial corrosion forming layers 13, 14 diffuses and the diffusion layer of the zinc is formed on the core member 11. At the same time, the zinc in the first sacrificial corrosion layer 13 and the same in the second sacrificial corrosion layer 14 may be secured to form the sacrificial corrosion layers, in which the Al-Zn alloy only is corroded, whereby the corrosion of the core member 11 may be prevented.

Title: Removing agent for rain drop on glass
Inventor: MURACHI MASATOYO
IPC: C09K3/18
Filed: 1990-08-30
Abstract: PURPOSE:To obtain a removing agent for rain drops depositing on glass, which is cheap and safe for human body and has no flammability or firing property by adding a water-insoluble adhesive material and surfactant to a sodium silicate aq. soln. CONSTITUTION:The removing agent is an aq. soln. essentially comprising a sodium silicate soln. to which water-insoluble adhesive material and surfactant are added. By applying this soln. on a glass surface, rain drops depositing on the glass is made to flow and removed, and this effect can be maintained for a long time. As one example of the water-insoluble adhesive material, sodium polyacrylate aq. soln. is used. Since sodium polyacrylate has large water absorption, swells into a gel by absorbing water, slowly dissolves in a long time, and moreover, has large viscosity, the coating layer can be made thick. By adding a surfactant thereto, flowing of the removing agent can be prevented to a certain extent.

Title: Gas stopper device
Inventor: KOBAYASHI KEIICHI
IPC: G08B21/00
Filed: 1992-08-28
Abstract: PURPOSE:To make possible reusing gas after the elimination of stop cause without a manual operation for opening by providing an automatic reset circuit which automatically opens a stop valve after a certain time from the gas stop in abnormality, continues opening while gas does not flow and stops again when the gas flows. CONSTITUTION:The safety circuit of a gas meter always monitors gas use rate, use pattern, earthquake and pressure, and in the case of any abnormality, a stop valve is shut. Once the stop valve is shut, an automatic circuit operates and the time after the stop of the valve is counted at first. For example, three minutes is set, after elapsing this time, the stop valve is once opened to monitor the gas flow. If there is a flow, it judges that the abnormality still exist, shuts the stop valve again and counts time again. After repeating this three time for example, if there still is gas flow, it terminates the counting for automatic reset. In the case no gas flow is observed after opening the valve, the abnormality is regarded recovered, and the stop valve is kept open.

The corrdinates X and Y of the points 3 and 4 on the screen when the body to be checked 1 is located at the position of solid lines are made to Xa0, Xb0, Ya0 and Yb0. The coordinates when the body is located at the position of dotted lines are made to be Xa1, Xb1, Ya1 and Yb1. Then by using the expression K1{(Xa0-Xb0)<2>+ (Ya0-Yb0)<2>}<1/2>=K2 {(Xa1-Xb1)<2>+(Ya1-Yb1)<2>}<1/2>= L, coefficients K1 and K2, which convert the unit distance on the screen into the actual unit distance of the position of the body to be checked 1, are continuously obtained. Thus the displacement of the actual position can be accurately obtained based on the position of the image of the body to be checked 1 and the screen.
